Why the urge to upgrade?
Are you not completely satisfied in the Tyros2? If not...what is it lacking?

I buy a lot of boards too, but none to replace my choice (G70)..I buy only as a back up or a new toy...

I do not understand swapping out one Tyros for another....As many have mentioned not a lot of differences...it looks like folks are looking for something they don't have in their current board...

Just an observation...don't slam me , I am not in the mood.. I have to drive a long distance in the rain to my gig....ahh, but there sits my G70.. ..waiting for me..
